Application filed April 23, 1924.

T0 all whom t may concern:

Be it known that l, TrroMAs D. BRENNAN, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain .new and useful Improvements in Oil Burners, of which the. following is a specification.

My invention relates lto improvements in oil burners.' f

An important object ofthe invention is to provide a lburner of the above .mentioned characterJ which .is'adapted to successfully` employ Al'asiffueh' any kind of low grade olistillate, or light gasoil,` as Well as fa high grade fuel, sucha's kerosene or coal oil.

A further" object of the invention is, to provide "al burner of the abovementioned character, which is particularly adapted for use in the furnace ofa heating-plant, such as Within. ai steam or hot Water furnace, hot air furnace, or the like. i

A furthergobject of the invention is to provide a device ofthe above mentioned charactenivhich is of simplified construction, and mayr be mounted Within/the ordinary furnace, ivithout altering the construe tion of the same. i

A furtherobj'e'ct of thefinvention is t0 proyidea bnrnenof the above mentioned character, having a vaporizing chamberar`Y ranged for and serving as a deflector for Vthe flame, causing the Vsame to travel radially in proper'proximi'tytothe vvall of the fur nace. r

A further object ofthe invention is to lprovide a burner of'the abovemmentioned character, .'liavingl means vivherebv the liquid fuel is thoroughly "vaporiged, and maintained in the vaporized"condition, until ith is suppliedfto burner tip or orifice.

Other objects and advantages of the iiivention `Will bel apparentduringrthe course of the following description.

through the usual construction, having a lire box 11, fuel door 19 slicer door 13, grate 14, ash pitl',

and ash pit door 16. This is of course the usual construction.

My burner device embodies a single.com-fh mon liquid-fuel supply pipe 17f,iWhich maya',-

be led in through the openingof the ash piti: and passed upwardly between the grate bars 14, or through the spaces .occupied by them, if they are with a tank (not shown) vholding the liquid fuel, which may be supplied through the' removed. The pipe 17 connects V pipe by gravity or by pressure,- ifdesired.

The pipe 17 extends centrally through ,a priming pan 18, which is horizontally arranged, and may be located upon the grato. bars 14. Above this priming pan, the pipe 17 is connected With radial branches 19,.preferablyarranged in the same vertical plane as the diameter of the pan. :The radial` klmanches 19 are bent at their outer ends, as

shown at 20, providing upstanding or vertical risers 21, which carry at their upper ends inwardly extending upper, radial 22, preferably arranged in thev same vertical plane as the diameter ofthe panlS,

and in the same vertical plane as the,v

branches 19. The upper radial branches 22;'

lead into the bottom of a combined deflector and vaporizing chamber y.Thischamber is closed at its top and bottoni, .atitsf.

sides, excepting for itsconnectionswvith the l 18, is arranged above it, and .is coaxialvvith relation thereto. f The vaporizing .chamber', v 23 of smaller diameter thanthe priming, pan 18, and it is preferred that .thel priming pan have a slightly larger diameter than thej length ofthe lower branches 19, vvherebythe` burning' of the liquid fuel Withinthis print,V ing pan may thoroughly heat the branches liet;

tally arranged, shown. ltwill be e that the branch pipes radiate with respect to the vaporising clieinbern sind ere spaced from each other :it an tingle ot The radial branches 2G are connected their inner ends with a. ya ve honefnnl 2i', provided in its top with an outlet opening' 28, and atvits bottom with e stnitling 'non 29. A vertically movable. needle vulve controls the escape ot vapor or ges t theV openingl 28. ,ett its lower end, the valve 3l has lelterel extension 32, opereting Within a slot 33, tamed in a *vertically swinging lever 34B This lever is pivoted at 85, and may extend to the exterior ot the furnace, for convenient manipulation.

From the foregoing description it is thus seen that the branches 19, und risers 21, constitute in effect an upstandinp,- Frl-shaped pipe, with the extensions 22 connected with the chamber 23. ln n similar Jenner, the branches 26 und pipes 25 constitute n substantially lshaped pipe, leading into the top 01"' the chamber 23, through the medium ot the extensions 24.

The operation et the burner device is follows:

The burner is mounted within the 'turiince or boiler, as clearly shown in Figure l, sind no housing is employed tor the burner. rlhe liquid fuel, passes upwardly through the vertice-l pipe l?, and travels through the branches 19 and passes upwardly tln'ouejh the risers 2l. In start-ing; the burnerdevice, it suitableamount et the liquid fuel is introduced into the priming` pen 18. and this liquid fuel is ignited. The thune Ytherefore passes upwardly, in Contact with, or in close proximity to,r the risers 21, und :ill other parts of thel burner. whereby the liquid fuel is vaporized, and the vapor discharges from the opening` 28, nt which pointit will be ignited. VNomeuns is provided to mixV nir with the 'vaporized liquid fuel. prior to the discharge ot the vapor 'troni the opening 28, as this mixing is effected upon such discharge, between the opening` 28 end the bottom ot the viiporizing' chamber since the air passes freely to the flame, through the grate.. The volume ot gas is oi course re'r.-

lated 'ley the movement oi the valve or. in turn shifted by moving,` the lever 34. The

flame passes upwardly from the opening:

28, andimpinges upon the bottom of the veporiging chamber 23, and is deflected horij Q3 various pipes are retained heuted hy contact 'with the thune or euses, und the vaporized tuel is maintained in the proper vnpor- ','ed torni end is prevented trom cmidensiul'.

prior to its discharge to the outlet opening QS. lt is thus seen that substiuitiully :ill parte ot the device are subjected to the direct action ot the iizune or heated und these parts will not he injured by the heut. since the interior thereot is constantly filled with either the liquid fuel, or the vnporized liquid ituol. rllhe nrraneenient ot the pipes or branches. radially about the combined detlector und vzrporizing chamber, increases the erlieiency ot the device, :is the maximum heet is imparted to these ports, `tor n thorough veporization ot the liquid tuel. By apjvilyinf the tull heat trom the burner or opening? QS. to the bottom ot the vuporizinf; elnunher Q?, entirely satisfactory vnj'ioriizition ot the liquid or oil is obtainable.

i'egjnrdless ot whether or not the burner is opernting :it its 'Full cnpnoity, or turned down to its lowest' point. This is the oh-4 ject that everyone is seeking'. who is inI terested in the development ot :in oil burner. ot this general typo.l :is it will ennhle the burner to he adjustable. tor producing' n heut ot any desired degree, within its rnne'e ot fidjustment.

lt is to be understood that the torni ot my invention herewith shown and described. is to he teiten ns u pre'teilred example ot the sume.y und that various changes in the shape, size.. and arrangement ot ports. muy he. resorted to. without departing YFrom the spirit ot mv invention` or the scope ot th(` subjoined claims Hoving` thus described in vinrention. what l claim is:
